I had Kuhmo KU31s on my previous car. I bought them because they got really good reviews. They are middle of the road in terms of price, but perform like the more expensive tires. I rate them very highly and would buy them again.
Some web reviews and comments from tire shops say that they can get a little loud, but i havnt noticied this (i did 20,000km and there was still plenty of tread left).
